DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings and initially to FIGS. 2 and 3, an exercising device in accordance with the preferred embodiment of the present invention comprises a handle 31, at least one support member 20 secured on the handle 31, at least one rotation wheel 10 rotatably mounted on the handle 31 and rotatable relative to the at least one support member 20, and at least one elastic cord 50 mounted between the at least one support member 20 and the at least one rotation wheel 10 and extendable to provide a buffering effect to rotation of the at least one rotation wheel 10 when the at least one rotation wheel 10 is rotatable relative to the at least one support member 20.
In the preferred embodiment of the present invention, the exercising device comprises two support members 20, a rotation wheel 10 and a plurality of elastic cords 50.
The rotation wheel 10 is disposed between the support members 20. The rotation wheel 10 has a central portion provided with a shaft hole 11 rotatably mounted on the handle 31 and has a periphery provided with a plurality of through holes 12 to allow passage of the elastic cords 50. Preferably, the rotation wheel 10 is provided with a light emitter (such as an LED), an oscillation switch and a battery.
Each of the support members 20 has a disk shape. Each of the support members 20 has a central portion provided with a mounting hole 21 secured on the handle 31 and has a periphery provided with a plurality of through bores 22 to allow passage of the elastic cords 50.
The handle 31 is extended through the shaft hole 11 of the rotation wheel 10 and has two opposite ends each inserted into and secured in the mounting hole 21 of a respective one of the support members 20.
The elastic cords 50 are mounted between the rotation wheel 10 and the support members 20. The elastic cords 50 are extended through the through holes 12 of the rotation wheel 10 and the through bores 22 of each of the support members 20. The elastic cords 50 are affixed to the support members 20 respectively by a plurality of locking members 23. Each of the elastic cords 50 has a tubular shape. The locking members 23 are inserted into the elastic cords 50 and are locked onto the through bores 22 of each of the support members 20 so that the elastic cords 50 are locked onto each of the support members 20. Each of the locking members 23 has a size greater than that of each of the through bores 22 of each of the support members 20.
In operation, referring to FIGS. 6 and 7 with reference to FIGS. 2-5, the exercising device further comprises a holding member 40 mounted on the two opposite ends of the handle 31 to facilitate a user holding the exercising device. Preferably, the holding member 40 is a substantially U-shaped bracket. In such a manner, the user's two hands can hold the holding member 40 to move the rotation wheel 10 forward and backward in a reciprocal manner so that the user has to apply a larger force to move the rotation wheel 10 successively, thereby achieving an exercising effect to train and build the user's abdomen, arms and legs. At this time, when the rotation wheel 10 is moved forward, the rotation wheel 10 is rotated relative to the support members 20 forward to stretch the elastic cords 50 so that the elastic cords 50 are extended to provide a buffering effect to rotation of the rotation wheel 10. In addition, when the rotation wheel 10 is moved backward, the rotation wheel 10 is rotated relative to the support members 20 backward by the restoring force of the elastic cords 50 so that the rotation wheel 10 is moved backward easily and smoothly by aid of the elastic cords 50. Thus, the elastic cords 50 provide a buffering effect to decelerate the forward movement of the rotation wheel 10 and provide a pulling force to accelerate the backward movement of the rotation wheel 10 so as to balance the forward and backward movement of the rotation wheel 10 and to prevent the user from being hurt during the reciprocal movement of the rotation wheel 10.
Accordingly, the elastic cords 50 are mounted between the rotation wheel 10 and the support members 20 to provide a buffering and damping effect to decelerate the forward movement of the rotation wheel 10 and to provide a pulling force to accelerate the backward movement of the rotation wheel 10 so as to balance the forward and backward movement of the rotation wheel 10 and to prevent the user from being strained or hurt during the reciprocal movement of the rotation wheel 10. In addition, the elastic cords 50 provide a buffering effect to decelerate the forward movement of the rotation wheel 10 and provide a pulling force to accelerate the backward movement of the rotation wheel 10 to balance the forward and backward movement of the rotation wheel 10 so that the user can operate the exercising device easily, smoothly and long.
Referring to FIGS. 8-10, each of the support members 20 is an upright plate, and the support members 20 are combined together so as to form a substantially U-shaped frame to support the handle 31 and the rotation wheel 10. The exercising device further comprises a pull cord 60 mounted around the rotation wheel 10, and a holding member 40 connected with the pull cord 60. Thus, when the user applies a pulling force on the holding member 40, the pull cord 60 is pulled by the holding member 40 to drive and rotate the rotation wheel 10 relative to the support members 20
Referring to FIGS. 11-13, the exercising device comprises a support member 20, two rotation wheels 10 and a plurality of elastic cords 50. The rotation wheels 10 are located at two opposite sides of the support member 20. Each of the rotation wheels 10 has a central portion provided with a shaft hole 11 rotatably mounted on the handle 31 and has a periphery provided with a plurality of through holes 12 to allow passage of the elastic cords 50. Preferably, each of the rotation wheels 10 is provided with a light emitter (such as an LED), an oscillation switch and a battery. The support member 20 is a substantially inverted T-shaped rack to support the handle 31 and the rotation wheels 10. The support member 20 is disposed between the rotation wheels 10. The support member 20 has a central portion provided with a mounting hole 21 secured on the handle 31 and has a periphery provided with a plurality of through bores 22 to allow passage of the elastic cords 50. The handle 31 is extended through and secured in the mounting hole 21 of the support member 20 and has two opposite ends each extended through the shaft hole 11 of a respective one of the rotation wheels 10. The elastic cords 50 are extended through the through holes 12 of each of the rotation wheels 10 and the through bores 22 of the support member 20. The elastic cords 50 are affixed to the rotation wheels 10 respectively by a plurality of locking members 23. Each of the elastic cords 50 has a tubular shape. The locking members 23 are inserted into the elastic cords 50 and are locked onto the through holes 12 of each of the rotation wheels 10 so that the elastic cords 50 are locked onto each of the rotation wheels 10. Each of the locking members 23 has a size greater than that of each of the through holes 12 of each of the rotation wheels 10. The exercising device further comprises two pull cords 60 mounted around the rotation wheels 10 respectively, and two holding members 40 connected with the pull cords 60 respectively.
Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
